“We dig deep to help those who need it most and I hope we can help raise awareness to the appeal and lend a helping hand.”
Murphy has returned to racing just weeks after back surgery for the first of the endurance races in the V8 Supercars Championship Series.
Along with co-driver Tim Blanchard, the pair will start today's 500km race from 22nd position.
The L&H 500 will start at 1.35pm.
